Abstract: A join process (Fig. 5) is disclosed for a wireless mesh topology network. In the network, nodes have multiple spatial coverage sub-sectors together covering a larger sector angle and a node can establish connection with other nodes located in directions covered by its sub-sectors. The join process (Fig.  5) adds a joining node to the network and includes having the joining node listen (504) to sub-sectors at a specific receiving frequency for a defined time. Thereafter, the network node changes (506) its sub-sectors and its receiving frequencies according to a defined timing and sequence. Active network nodes transmit (508) organized invitation data packets on defined sectors, frequencies and timing, based on relative location and relative angle orientation deduced from sub-sectors already in use for existing internal network communication. This reduces frequency interference in the network and reduces time required for the join process.

Abstract: A piezoelectric drive, and the rotor and/or pushers thereof, have long life, e.g. at least about 6000 hours of actual operation. The piezoelectric drive also is highly accurate, and is relatively inexpensive to make. The rotor friction surface and/or pushers are made from a material having a low mechanical quality factor, yet with high strength and stability under the conditions encountered in the ultrasonic fields typical of piezoelectric drives.  The material is preferably a semi-crystalline thermoplastic polymer (e.g. polyarylamide) with filler (e.g. glass particles or fiberglass), e.g. about 30-60% polymer and about 40-70% filler, and can easily make injection molded components or parts or components. A pair of drives may be connected together to form an instrument, for example rotating a shaft connected to a pointer of analog instrument either clockwise or counterclockwise. Analog instruments, such as thermometers, barometers, speedometers, altimeters, pH meters, anemometers, etc., or other precision devices may utilize the piezoelectric drive. Alternatively, the piezoelectric drive may drive other mechanical devices such as gears, encoding locks, servo systems, point of purchase devices, micro pumps, clocks, timers, etc.
